Pittsburgh has this rich industrial past, when it was the heart of the U.S. steel industry, and it burned out as the industry burned out and moved elsewhere.
There was a long period of time when Sam Fuller had a lot of projects fall through and had a lot of difficulties getting a project off the ground. And I was able to observe him during that period, and see his incredible resiliency and courage as he faced this difficulty and just kept working.
It was just a wonderful experience, one for the memory book for sure. The sad thing about it was that the picture came under this absurd cloud of controversy. Here was a movie based on the central theme that racism is something that is taught, and it's illustrated by this story of a dog and the efforts of humans to re-train it after it had been trained to go after black people. And it created this ridiculous controversy and wound up being the last Hollywood movie that Sam [Fuller] made.
Movie stars exaggerate certain things to let the audience know they're just playing a character, as if they're saying, "Look at me, I'm not really an old man, I'm just playing one." Or "I'm not really a homosexual, I'm just playing a gay character. Or an alcoholic. Or somebody who's mentally impaired." They often do it very successfully and win awards for it.
From my point of view, when I was thinking about the prospect of [Michael Douglas] in this part, I wondered if he would go all the way with it. The reason I was concerned is that, oftentimes, actors - especially movie stars - when they're playing a character who might be perceived as unattractive or eccentric, will wink at the audience while they're doing it.
